Setting Up Tax Tables How to Set Up a Tax Table

4 Complete your worksheet, indicating the amount differences and the tax
differences for each range of taxable amounts.
5 Examine the Amt Diff column on the sample worksheet. Note that there is a
regular pattern. Five $0.18 taxable amount increments are followed by one
$0.19 increment, then there are four $0.18 increments, and one $0.19 increment.
This pattern repeats-or loops-itself eight times. Now examine the Amt Diff
column of your worksheet. Try to find a repeating pattern in the tax amount
increments.
6 Find a repeating pattern to the increments in the Tax Diff column (it may be that
they are always the same, as in the sample).
7 Then find a single repeating pattern that accounts for the increments in both Diff
columns. If the increments in the Tax Diff column are not all the same, this may
be more difficult, and the pattern will almost certainly repeat itself less often.
You will use the repeating patterns you find to build the tax table through the
TAX program.
To compose your compressed description, write down:
• The tax number (1-8: defined in configuration).
• The tax type. For tax tables, it is type 1 or 2.
• The method for figuring taxes on amounts that exceed the largest amount in
the table: you can use a fixed rate with a rounding rule, or you can apply the
table to the excess amounts.
• The tax increment; almost always 1 cent.
• The smallest taxable amount.
• The formula for determining the individual entries in the table. You do this
by means of three TAX program commands: increment, loop, and end loop.
An increment tells the TAX program an Amt Diff and a Tax Diff and the number
of consecutive times to apply those differences. For example, in the sample
worksheet, the first Amt Diff is 0.18, and that difference occurs five consecutive
times. For the sample table, and for most tax tables, the tax increment is always
$0.01.
A loop tells the TAX program to repeat the commands within the loop the
number of times you specify. You start a loop with a loop command and end it
with an end loop command. So, when two or more increments occur in a
repeating pattern, you can describe the repeating pattern in terms of a loop.
Loops may be nested-that is, the steps repeated by a loop may include other
loops.
An end loop terminates the last loop that was started. Thus, if there are two loop
commands and then an end loop, the end loop will terminate the second loop.
Another end loop is required to terminate the first loop.
